Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a key operation type locking device used for a lid for opening and closing a glove box of an automobile.

[0002]

[Prior art]

 As a conventional locking device of this type, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 61-147875. Although not specifically shown, the conventional locking device includes a frame with a cylinder lock fixed to the lid of the glove box, and an opening / closing knob integrally formed with a pressing claw on the back surface of the frame. And a lock claw releasably engaged with a striker provided on the box side, and a joint claw connecting the lock claw and the opening / closing knob are rotatably supported respectively, while opening and closing A connecting hole is formed in the base end portion of the operating lever that also serves as the rotary shaft of the knob and the joint pawl, and the eccentric shaft provided at the rear end of the cylinder lock is loosely fitted in the connecting hole. With the rotation of the cylinder lock, the joint lever is moved to a position where it interferes with the pressing claw portion of the opening / closing knob and a position where it does not interfere with it, by moving the operating lever.

In actual use, by operating the key, the cylinder lock is rotated in the unlocking direction so that the joint claw pivotally supported by the operating lever interferes with the pressing claw of the opening / closing knob. After that, the opening / closing knob is pulled up against the spring pressure of the return spring, and the joint claw is rotated downward by the pressing claw portion of the knob. The lock claw rotates downward against the biasing spring pressure to automatically release the engagement locked state with respect to the striker, so that the lid is guaranteed to be opened. Also, when the cylinder lock is rotated in the opposite locking direction, in this case as well, the operating lever moves in conjunction with this, but this time the joint pawl pivotally supported by the operating lever opens and closes. Since it will move to a position where it does not interfere with the pressing claws of the operating knob, in this state, no matter how much the opening / closing knob is pulled up, the pressing claws of the knob will idle and the joint claw will move downward. Since the lid is not rotated, the closed and locked state of the lid is guaranteed.

[0004]

[Problems to be solved by the device]

 Therefore, with such a conventional lock device, it is possible to ensure the locked / unlocked state of the lid for the time being, but on the other hand, the opening / closing knob, lock claw, joint claw, and Since the actuating levers and the like must be molded separately and the respective parts must be individually assembled to the frame, the number of parts naturally increases accordingly, and the device itself becomes unnecessarily large. The assembly work was extremely difficult, and there was a big problem that the cost was increased. In the past, it is theoretically possible to prevent the opening / closing knob, lock claw, etc. from being damaged due to erroneous operation if the opening / closing knob is idle when the lid is locked and locked. However, in actual use, on the contrary, it may be difficult to judge whether the lock is locked or the cylinder lock side is broken, so the occurrence of troubles due to such a judgment error could not be denied. .

[0005]

[Means for Solving the Problems]

 The present invention was developed in order to effectively solve the problems of the conventional locking device. Therefore, a frame with a cylinder lock fixed to the lid side and an opening / closing knob rotatably attached to the frame are provided. On the premise of a lid locking device including a lock means for engaging a striker provided on the box side, the locking means is integrally provided on the opening / closing knob, and the locking means is operated by operating the opening / closing knob. Is configured to be directly rotated in the direction of disengagement from the striker, while the eccentric shaft of the cylinder lock is connected to the base end of the stop lever so that the working end of the stop lever interferes with the locking means. We adopted a configuration to move it to a position where it does not interfere.

[0006]

[Action]

 Therefore, in the present invention, the locking means for interlocking with the rotation of the knob is integrally provided on the opening / closing knob side, and the stop lever for interlocking with the rotation of the lock is connected to the cylinder lock side. Then, when the cylinder lock is unlocked, if the working end of the stop lever is moved to a position where it does not interfere with the locking means, the opening and closing knob can be operated to ensure the normal opening and closing of the lid. In the locked state of the lock, if the working end of the stop lever is moved to a position where it interferes with the locking means, even if an operator tries to operate the opening / closing knob, the working end of the stop lever causes the locking means to move from the striker. Since it can be prevented from rotating in the detaching direction, this ensures that the lid is locked and locked.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to an illustrated embodiment. A locking device according to the embodiment is also developed as a lid locking device provided in a glove box of an automobile, and has a basic structure. As shown in FIG. 1, a frame 1 made of synthetic resin fixed on a lid (not shown) side is provided, and a cylinder lock 2 is supported on one side of the frame 1 and a front side of the frame 1 is supported. It is premised that the opening / closing knob 3 is rotatably attached to the opening / closing knob 3. However, the feature is that the opening / closing knob 3 side is provided with a locking claw 4 as a locking means, and the cylinder lock 2 side is provided with the locking claw 4. The stop lever 17 for preventing the downward rotation of the lid 4 is connected, and only the action of the stop lever 17 and the lock pawl 4 guarantees a reliable unlocked state and locked state of the lid.

Therefore, first, the relationship between the opening / closing knob 3 and the frame 1 will be described. In the present embodiment, as shown in the figure, the opening / closing knob 3 is provided on the box (not shown) side at the center of the back surface. A horizontal J-shaped lock claw 4 that engages with the striker in a disengageable manner from below is integrally projected, and a pair of connecting holes 5, 5 are integrally formed on both side edges of the knob 3, while the other is formed. A window portion 1a is formed in the center of the frame 1 so that the lock claw 4 faces rearward, and the connecting hole portion 5 of the knob 3 is provided on the front surface of the upper portion of the window portion 1a as shown in FIG. To form a pair of connecting shaft portions 6 and 6 to be fitted to and a pair of mounting shaft portions 8 and 8 to which a torsion spring 7 for constantly urging the lock claw 4 upward is attached, and to form the window portion 1a. On the rear side of the upper side, a lock wall 9 that cooperates with the lock claw 4 to define the storage part of the striker is integrally formed. A stopper wall 10 is formed on the rear surface of the lower side of the window 1a so as to project and to prevent the lock claw 4 from rotating downward. A damper rubber 11 having a flexible shape is fixed to the lower surface of the lock wall 9 to prevent the generation of engagement noise with the striker and rattling. .

Therefore, the locking device of the present embodiment obtains a state in which the torsion spring 7 is mounted on the pair of mounting shaft portions 8 and 8 and the pair of connecting shaft portions 5 is formed in the connecting hole portions 5 of the opening / closing knob 3. By simply fitting the parts 6 and 6, the opening / closing knob 3 can be easily attached to the front surface side of the frame 1, and the striking operation can be performed only by the rotating action of the lock claw 4 which is interlocked with the operation of the opening / closing knob 3. Locking and unlocking can be performed automatically.

Next, the relationship between the stop lever 17 and the cylinder lock 2 will be described. In the present embodiment, an eccentricity provided on the rear end wall 2a of the cylinder lock 2 at the base end portion 17a of the stop lever 17. A connecting hole 18 for loosely fitting the shaft 12 is bored, an eccentric shaft 12 is loosely fitted in the connecting hole 18, and the cylinder lock 2 is rotated in the forward and reverse directions. The portion 17b is configured to be movable to a position where it interferes with the lock claw 4 and a position where it does not interfere, and an elastic piece 19 is integrally formed below the connecting hole 18, and a tip pin 19a of the elastic piece 19 is formed. By elastically overhanging the convex portion 13 provided on the frame 1 side, it is possible to easily confirm the unlocked state and the locked state with a clear feeling of moderation. Cylinder lock on the lower edge of the center The guide piece 17c for the rear end wall 2a is formed.

In the figure, 14 and 15 are an upper guide wall and a lower guide wall for guiding the movement of the action end portion 17 b of the stop lever 17, and the former upper guide wall 14 is located on the rear surface side of the frame 1. It is provided directly, and the latter lower guide wall 15 is connected to the stopper wall 10. Reference numeral 20 is a restriction arm that collides with the stopper portion 16 on the frame 1 side, and is integrally provided on the side edge of the rear end wall 2a in order to restrict the rotation area of the cylinder lock 2.

Therefore, in the lock device according to the present embodiment, the independent lock claws, joint claws and their attached parts as in the conventional case are completely unnecessary, so that not only the number of parts can be greatly reduced. After the eccentric shaft 12 is loosely fitted in the connecting hole 18, the base end portion 17a of the stop lever 17 is assembled to the cylinder lock 2 side, while the torsion spring 7 is attached to the pair of mounting shaft portions 8 of the frame 1. When the mounted state is obtained and the lock claw 4 is exposed to the inside of the window portion 1a, the connecting shaft portions 6 corresponding to the respective connecting hole portions 5 of the opening / closing knob 3 are forcibly fitted to each other. As shown in FIG. 7, the device itself can be quickly assembled, so that the assembling work can be greatly simplified as compared with the conventional locking device.

When the cylinder lock 2 is rotated in the unlocking direction by a key operation during actual use and the locking device is in the unlocked state, the cylinder lock 2 is rotated as shown in FIG. In conjunction with this, the stop lever 17 moves to the left in the figure, and the working end 17b of the lever 17 is completely separated from the lower portion of the lock claw 4 (interference position). After that, as shown in FIG. When the operating knob 3 is pulled up against the spring pressure of the torsion spring 7, the lock claw 4 provided integrally with the knob 3 rotates downward, and the engagement locked state with respect to the striker 21 is immediately released. As a result, this will prevent the opening of the lid. In addition, when the cylinder lock 2 is rotated in the unlocking direction by such a key operation, the tip pin 19a of the elastic piece 19 described above moves over the convex portion 13 to move, so that a clear click feeling is obtained. Although it will be obtained, this phenomenon is the same when the cylinder lock 2 is rotated in the locking direction.

In addition, when the lid is closed under such an unlocked state, if the lid is moved in the closing direction, the striker 21 is locked by the striker 21 with the rotation of the opening / closing knob 3. 4 is forcibly rotated downward to enter the storage portion defined by the lock claw 4 and the lock wall 9 from the opened opening, and again receives the spring pressure of the torsion spring 7 to strike the striker. 21 is engaged and locked by the lock claw 4, so that the closed state of the lid can be easily obtained. Moreover, in this embodiment, since the lock claw 4 provided integrally with the opening / closing knob 3 directly engages with the striker 21, the engagement force with respect to the striker 21 is also improved.

On the other hand, when locking the lock device to prevent theft, if the cylinder lock 2 is rotated in the opposite locking direction by a key operation, the cylinder lock 2 is rotated as shown in FIG. This time, the stop lever 17 moves to the right in the drawing in conjunction with, and moves to the position where its working end 17b interferes with the lock claw 4, that is, immediately below the lock claw 4. Then, for example, even if the lock claw 4 of the knob 3 is pulled up and the lock claw 4 of the knob 3 is rotated downward, as shown in FIG. It completely prevents the lower part from rotating downward, so that the locked state of the locking device is surely guaranteed, and there is no fear that the lid is opened. Moreover, when the lid is in the locked / locked state, the stop action of the stop lever 17 prevents the open / close knob 3 from idling, so that the locked state of the locking device can be directly confirmed. As in the conventional case, there is no need to worry about whether the cylinder lock 2 is locked or the cylinder lock 2 is out of order.

[0016]

[Effect of device]

 As described above, the present invention ensures a reliable unlocked state and locked state of the lid by adopting an extremely simple structure, unlike the conventional locking device that requires a large number of parts by adopting the above configuration. Therefore, it is possible not only to contribute to cost reduction while also reducing the number of parts and the number of assembling steps associated therewith, but in particular, to greatly contribute to downsizing of the locking device itself. . Moreover, in the present invention, the structure in which the opening / closing knob is not swung by the action of the stop lever allows the locked state of the lock device to be directly confirmed. Since it is difficult to judge whether the lock is out of order, it is possible to prevent the occurrence of troubles due to such a judgment error.
